Problem: Yolks Break Easily or are Broken Inside Egg - Page 4

I just started getting some of my eggs with yolks that are thin and breaking. The hens are less than 2 years of age. The only change in their diet was that I switched from regular crumbles to organic pellets with no other changes. They have easy access to oyster shells and same amount of treats are given each day. I tempted to go to organic crumbles to see if I see a change.
